Node access rules are not honored

Hello, awesome module. This is exactly what I needed to setup our two sites, one of which is the "main" site, the other which is the Shopping Cart system - so I have shop.example.com and www.example.com (root). The Shopping site is a previous Drupal solution, and the new Drupal Main site is a migration - so I'm "reverse-engineering" the main site, in a way. So far everything is working out, the only issue I have is this:

I've read the Install and Readme files, all the patches have been applied successfully. However neither anonymous nor authenticated (non-Administrator) users are able to see the content. I receive either a "You must login" screen or "You are not authorized to access this page" screen when I attempt to view it as the authenticated user.

What I'd like to do is have Products be viewable only on the Shopping Cart site, of course, but right now they are visible on both - as long as you're an Administrator.

All of my previous content shows up fine, albeit on both sites which is not what I want; but it appears that the only way to get the nodes to show up is by selecting "Show to all affiliates" - and when I select a specific affiliate, the content disappears from both.

Any ideas? Did I miss something - maybe there is another area or bit of code I can check? Any help is greatly appreciated.
